Question 2.4: Write the complete symbol for the atom with the given atomic number (Z) and atomic mass (A)
(i) Z = 17, A = 35 (ii) Z = 92, A = 233 (iii) Z = 4, A = 9
Ans 2.4: For any given atom, we can write the symbols as AZX. Here, X is the element’s symbol, Z is its atomic number and A is its mass number.
Therefore the symbols for the above elements are written as:
(i) Z = 17, A = 35
(ii) Z = 92, A = 233
(iii) Z = 4, A = 9
